Microsoft has just announced the latest version of its health and fitness wearable, the Band 2. Compared with the 2014 model, the fresh take on the personal gadget is more capable and feels much more comfy on the your forearm than its predecessor, but comes with a higher price tag. The Band 2 is challenging the other major players in the wearables market (Apple, Fitbit and Jawbone) especially when it comes to battery life, claiming that the Band 2 will last 2 days under normal use. As with the previous version, the gadget works with Windows, Android, and iOS operating systems. One of the most noticeable changes to the new model is that it has a much sleeker appearance than that of its predecessor, with a screen that curves around the wrist strengthened with Gorilla Glass 3 and a wristband that is much softer. As for the incorporated tech, whereas the first Band had a decent set of heart rate and step monitors, the new unit also includes an atmospheric pressure and elevation sensor that is useful on hiking treks. In addition, the Band 2 is fitted with a monitor for VO2 Max, which is an advanced metric of fitness that normally requires costly equipment to compute. The Microsoft Band 2 also supports a wider range of smartphone apps when it comes to their alerts and it even has a shot-tracking capability for golf enthusiasts. Speech support for Cortana, Microsoft’s electronic smartphone aide, has been added too. The company says that the Band 2 will be in US shops by the end of October.
